A virtual private network (VPN) is a network that uses a public telecommunication infrastructure, such as the Internet, to provide remote offices or travelling users access to a central organizational network securely. VPNs encapsulate data transfers using secure cryptographic methods and other security mechanisms to ensure that only authorized users can access the network and that the data cannot be intercepted.

Hi Guys,

We have recently setup a 3 way VPN. one HQ and 2 Branches. 2 sites are configured with NBN and fibre 400. One site is with ADSL2+. IPsec VPN between NBN site and Fibre400 is working fine. But, the ADSL2+ site is showing that the VPN is configured and online but, not able to ping any IP either way. Any idea why?

Regards,

Ajoy

Hi,

I have a question regarding remote users and security.

Which one is better or the standard way?

1. VPN and RDP to a inside computer
2. VPN without RDP, but more restrictions through ACLs.

What is the way to go? PS: We have extremely sensitive PII information.

Thank you in advance!

Hello Experts
I was recently appointed as IT Manager at one of the companies.
This company is using microsoft CRM.
The former Director of Information Technology used traditional VPN technology from Internet service providers to connect all the company's branches around the country. Which cost the company a lot of money per month.
While this VPN is only used to run that program in these branches.
What I think if I can develop or modify this system to use cloud technology or any thing else To reduce costs and also to develop the company

Dear Experts,
We just installed Cisco ASA 5506X and are using Cisco AnyConnect Secure Mobility Client.
What I am having trouble is, in order to get to the server drive, the user is always prompted for credential, and I can only use NetworkAdmin credential to get in.
Mapped drives do not work once in VPN, so I started to use specific file path. (\\FileServer\Shared Folder\Documents)

I am not sure why the mapped drive stopped working, but more importantly, isn't there a way to remove this authentication at the server level?  None of the users have to put in the credential when they are in the office.
The server OS is Windows Server 2016 Essential.    
Please advise.

Sounds strange:
I have an VPN to a foreign network which is established by the two routers.
The network mask is 255.255.255.0
I can't ping the computer with the address x.x.x.1
I can ping every other comuter in the foreign network.
I can establish a RDP connection to x.x.x.1
I can't reach the x.x.x.1 through port 1433 (SQL)
From a computer inside the foreign network everything works fine which does'nt work through the VPN.

This behaviour ist new. A couple of days bevor, everything worked fine.

I have no idea!

What is the reason for having a time limit set for inactivity set on a VPN connection?

I'm putting together a strategic plan for our department and this is one of the issues that came up and I'm attempting to put together the reasons as to why this is done, but would like other's insight.

Thank you

I am trying to find a solution for a client which will allow them to push all SSH traffic over remote access VPN? they are also requesting that it must have split tunneling and all http/https traffic must go out over the local internet. Is this even possible? they currently have a fortigate, which says no its not possible, I've called a few other vendors who say their VPN solutions are not capable of that. I know in cisco you can force specific sites to go over the VPN but you need specific IPs and it is not recommend. OpenVPN might be able to do it but I might be misinterpreting what I'm finding. Has anyone come across something like this before and can point me in the right direction?

Basically this client has a lot of remote workers who download large images which is why split tunneling is a must. They work through AWS and SSH into the boxes. The security for this is getting out of hand as they have a lot of servers and they are putting everyone's public IP in the security settings to allow them to access the servers. They no longer want to do this and only use their public IP for security reasons so we are trying to get a baring on how one would be able to accomplish this as they want 1 point to cut all access to the servers if a user would leave or be terminated.

Hi Guys,

We have a couple of servers which we would like to transfer to a data centre.
Some servers however will stay onsite.

The primary DC will move the data centre, as well as the Exchange server.
The backup domain controller will stay in the office for user authentication, etc.

Users will access the the servers in the data centre via the web mostly.

My question
We will be configuring a site-to-site VPN to have the two DC's synchronise.

Will this be sufficient or are there challenges or risks which we should be aware off?

Ensure Business Longevity with As-A-Service
Ensure Business Longevity with As-A-Service

Using the as-a-service approach for your business model allows you to grow your revenue stream with new practice areas, without forcing you to part ways with existing clients just because they don’t fit the mold of your new service offerings.

My computer is part of the domain and when in the office I use Hyper-V manager on my local machine (windows 10 pro) to manage our Hyper-V hosts.     However when I am working out of office in my home office I connect to the office using a VPN client.    And although I have access to the servers through Remote Desktop my local Hyper-V manager will not longer connect to the servers to manage the hosts.     The error is RPC server unavailable.   I have researched this error and have yet to find the solution.

I have an SBS 2011 which runs exchange/DNS/DHCP/VPN but I had to remove the DHCP from it and use the routers DHCP for reasons that I cannot explain. Everything works fine but I cannot find anything online that says that VPN will work with an external DHCP.

I've just had my first remote user complain that she cannot connect so I rerun the fix my network and setup the vpn again and she appears to be connected fine. Is there anything else I need to check/do on the server or the router to ensure proper operation of the VPN?

MAC computer (macOS 10.14 Mojave) is able to successfully connect to corporate network via Anyconnect mobile vpn client. But when attempting to map a shared network drive to a windows server share it hangs and finally times out after 2 minutes or so and wont map the drive. Yet there are 6 other MAC's with macOS 10.14 Mojave that do not have this problem.

Tried pinging the windows server from the MAC after successfully connected to the VPN and it will continuously times out but there is a reply to ping every 15th ping request for about 2 pings and then go back to not responding to ping for another 15 pings.

When pinging MAC from the windows server it will ping successfully continuously!

I already plan on performing apple diagnostic on the MAC next but I am not too familiar with Macs and want to see if there are any other suggestions from the community!

Appreciate any other ideas....

Dear Experts,

We have configured SSL VPN for the Sophos XG 310 firewall to use.

When we tried to add a second ssl vpn account copying the first account settings, we are unable to connect.

Is there a log for SSL VPN?

Hi all, when I log onto my PC at work, my startup folder includes a PowerShell script. The script simply checks whether certain network drives are mapped; and if not, then map them. When I work from home, however, I have to VPN and manually authenticate before the network drives are revealed to me. I can add a time delay to my script, or wait for a manual key press.

I am thinking that the delay can be automated, possibly with a wait condition. Perhaps a ping to an IP address inside the firewall. If you have any suggestions to improve this, please let me know. One limitation, I do not have admin privileges on the PC.

User has two locations where they work on their photo library using Adobe LightRoom on Mac.  They are 8 months at first location, then 4 months at the second for the summer.

Can I have a Synology NAS at each location to synchronize their work?

Internet connection in NYC is FIOS, which currently is 600+ mbps using Speedtest both Download and Upload
Internet connection in MA (Massachusetts) is Xfinity which measures 30 Download and 6 Upload

They have about 5 TB of photos on a RAID directly attached to their computer.
I can use software to sync the RAID files to and from the Synology


I will do the initial synchronization of  the Synology units in NYC, and have them bring one to MA

Once in MA
User adds 1 to 2 GB of photos every few days, which will be synchronized to the NAS

At the end of the 4 months, when the user returns to NYC, I would like their photo library and LightRoom catalogs to be a mirror of what they were working on in MA, and ready to use.



Is this a good method?
Any steps missing?


Thanks

Hello Experts,

I have issue with an external client, he is using
a laptop with Cisco anyconnect vpn client and he would
usually connect to the vpn and would be able to browse the
internet and also access internal resources, shares and sites.

Today he connected from home and he was not able to browse anything,
I checked his laptop remotely and I was not able to ping google or resolve
any DNS names. To get him going I gave him default gateway IP in his VPN connection
but I am not suppose to do that.

My quest is why when he connects to vpN, the DNS stops.
I tried to replicate the issue using my hotspot and on my laptop
but i did not get the same symptons, my VPN does not give me GATEWAY ip and I
am able to browse plus access the internal resource.

I am certain this issue is local to his internet connection
at home.Please do let me know if anyone has any suggestions.

Thanks,

OWASP: Avoiding Hacker Tricks

Learn to build secure applications from the mindset of the hacker and avoid being exploited.

I have a new Server 2016 instance running the new AWS Lightsail platform.  I would like to setup a site to site VPN between the local office network and the server.  There isn't much documentation on VPCs with Lightsaol compared to EC2.  The subnet that the lightsail instance is on is restricted in the VPC config, 172.26.0.0/16 so I can add that subnet to the VPC. I can setup VPX peering between EC2 instances and lightsail but I can't figure out how to make the lightsail instance visible when setting up the VPN connection.

Currently we have a Cisco ASA 5512-x and we have split tunneling for VPN. Due to issues it's causing for many of our devs at home (they need to vpn into our network then route over to aws), we want to remove split tunneling.

  1. How do I go about removing split tunneling?
  2. Are there any got chas that I need to look out for? Will this potentially break routing anywhere else?

I don't have a deep understanding of networking, but I am comfortable getting into the Cisco ASA and making configuration changes.

RDP connection through VPN (SonicWALL) using dual monitors at home (Windows 10 Pro) and at the office (Windows 7 Pro).
From what I understand only Windows 7 Ultimate and Enterprise have dual monitor support.
Currently trying to setup UltraVNC.
If we were to upgrade to Windows 10 Pro at the office would it work?

I have a laptop which connects to a remote share over a VPN connection.   The connection was working and she was able to access the share while out of the office.    This weekend the share no longer worked and she could not get connected.    

The computer has been rebooted multiple times, the vpn connected has been terminated and restarted multiple times.    I can ping the remote server by name and IP, NSLookup returns the correct IP address and I can connect if I enter the IP address but not the server name.  

Any suggestions on why I can suddenly not map the drive by name?

I need some help explaining to a new boss that a remote connection to a native VFP9 database is not a good idea.
To date I have been insisting that remote users (few) VPN and create a RDC to their desktop at work, which is in the local domain with the server. No problems.
But the new guy has realized that once he makes the VPN connection he has access to the remote database and can run the VFP9 app directly from home.
Years ago I understood this was not a good idea because of latency and update issues but have have today's faster internet connections reduced/eliminated that problem?
We will be migrating to a packaged ERP system in a year or so, but I would like to keep the VFP9 database free from corruption until then!

What the heck, trying to set a VPN connection on a new MacBook Pro 7th gen. and VPN into a Linksys LRT224
On the Mac I go to network and create a VPN L2TP and use the following settings
Configuration: default
Server Address: (I use my ip address)
Account name: (I use the VPN account I set up on the Linksys)

Authentication Settings:
User Authentication: (I use the VPN account password I set up on the Linksys)
Machine Authentication:
Shared Secret: (Not sure about this so I just used the VPN account password)

Advance settings:
I tried "Send all traffic over VPN connection"

I get e message that the VPN server cannot be reached

I set this up on a Windows 10 and 7 PC and it works just fine
